Top vaccines/drugs in the pipeline for coronavirus treatment


Some of the major and busiest international airports in the world started announcing preventive safety measures against the spread of the 2019 Wuhan coronavirus, which the WHO calls Covid-19, after its outbreak in China and quick spread to 77 more countries.

The virus that was first found in Wuhan, the capital and the most populated city of Hubei Province, in Central China, has been spreading at a rapid pace despite various preventive measures being taken by the Chinese authorities. Deaths caused by the 2019 novel coronavirus (2019-nCoV) have been increasing at a rapid pace from the mere two reported initially to 170 in less than a month.

The reported deaths due to the infection more than doubled in four days to 362 by 02 February, and rose sharply to more than 1,800 as of 18 February. International passengers travelling from China are naturally the biggest risk to the countries they arrive to.

The US Department of State has issued level-4 travel advisory to China, meaning that the public is not advised to travel to China. The CDC earlier had issued a level-3 warning recommending to avoid travel, unless essential, to Wuhan and level-2 warning to the rest of China. But given the fast spread, the CDC revised the travel warning to level-3 for entire China.

Coronavirus impact on airlines operators

The International Air Transport Association (IATA) announced that the Covid-19 outbreak is expected to result in 13% full-year loss of passenger demand for airline operators in the Asia-Pacific region. The loss is expected to cause a revenue loss of $27.8bn in 2020 for the carriers.

Majority of the impact is projected to be on those carriers registered in China, who are expected to lose $12.8bn in the domestic market.

Coronavirus – how airports and airlines are ensuring a safe travel

The coronavirus has crossed borders, with cases confirmed in 25 more countries including the US, Canada, UK, Russia, Germany, France, Japan, India, South Korea, Hong Kong, Macau, and Thailand.

The CDC expanded the screening to 20 airports within a week due to the growing spread of the virus.

United Airlines announced the cancellation of a number of scheduled flights from US hubs to Beijing, Hong Kong, and Shanghai from 1 February anticipating lower demand due to the nCoV fears.

How airports perform thermal screening of passengers

Airports perform coronavirus thermal screening of passengers to spot fevers caused by infections such as CoV, swine flu, and influenza (such as H1N1). Thermal screening is performed using mass-screening systems that measure the skin temperature at high-speed using thermal imaging and temperature measurement equipment such as the FevIR Scan.

Such quick mass-screening ensures to take security measures without causing delays and discomfort to passengers.

Coronavirus symptoms

Symptoms of coronavirus infections can begin with simple cold and cough and mild fever, but aggravate if left untreated, leading to more severe respiratory illnesses such as pneumonia. Coronavirus transmission happens both through humans and animals such as dogs and cats.

Coronavirus vaccine

No vaccines exist currently to fight the coronavirus, but the National Institutes of Health (NIH) in the US is developing one but that would take at least a year to be available. A number of private pharmaceutical companies are also developing potential vaccines and drugs.

Coronavirus / MERS-CoV treatment

Most of the coronavirus drugs in the pipeline are at early stages of development, leaving anti-viral drugs used for other conditions as the only treatment options. A number of pharmaceutical companies have announced partnerships to develop coronavirus drugs for treatment.
